Abox contains five keys, only one of which will open a lock. keys are randomly selected and tried, one at a time, until the lock is opened (keys that do not work are discarded before another is tried). let y be the number of the trial on which the lock is opened. a find the probability function for y . b give the corresponding distribution function. c what is p(y < 3)? p(y ≤ 3)? p(y = 3)? d if y is a continuous random variable, we argued that, for all −[infinity] < a < [infinity], p(y = a) = 0. do any of your answers in part (c) contradict this claim? why?

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)

is this the complete
